Looking for polyurethane rigid foam panels

Hi there,

I need to do this very small insulation upgrade and we only have 3" to work with. (capital that we do not exceed that- don't ask me :censored:) I wanted to use polyurethane rigid foam panels as these have the best R-value from what I understand (R-7 to 8 per inch. I think the stuff is expanded with CFC's or HCFC's)

But I can't find the stuff here at all. I'm in the Montreal area in Canada and we only need a few. Any ideas?
Where would you guys look for those?

Or maybe some other product suggestion that will offer a comparable R value. (Like polyisocyanurate rigid foam insulation panels expanded with pentane (R-6.8 per inch) but no luck as well finding those...)


P.S. long time visitor here... ;)
